Uses of Map in java.security

Classes in java.security that implement Map

class

Provider This class represents a "provider" for the Java Security API, where a provider implements some or all parts of Java Security, including: Algorithms (such as DSA, RSA, MD5 or SHA-1).

Methods in java.security with parameters of type Map

static Provider[]	Security.getProviders(Map filter) Returns an array containing all installed providers that satisfy the specified selection criteria, or null if no such providers have been installed.
void	Provider.putAll(Map t) Copies all of the mappings from the specified Map to this provider.

Uses of Map in java.text

Methods in java.text that return Map

Map	AttributedCharacterIterator.getAttributes() Returns a map with the attributes defined on the current character.

Methods in java.text with parameters of type Map

void	AttributedString.addAttributes(Map attributes, int beginIndex, int endIndex) Adds a set of attributes to a subrange of the string.

Constructors in java.text with parameters of type Map

AttributedString(String text, Map attributes)
Constructs an AttributedString instance with the given text and attributes.

Uses of Map in java.util

Subinterfaces of Map in java.util

interface

SortedMap A map that further guarantees that it will be in ascending key order, sorted according to the natural ordering of its keys (see the Comparable interface), or by a comparator provided at sorted map creation time.

Classes in java.util that implement Map

class	AbstractMap This class provides a skeletal implementation of the Map interface, to minimize the effort required to implement this interface.
class	HashMap Hash table based implementation of the Map interface.
class	Hashtable This class implements a hashtable, which maps keys to values.
class	Properties The Properties class represents a persistent set of properties.
class	TreeMap Red-Black tree based implementation of the SortedMap interface.
class	WeakHashMap A hashtable-based Map implementation with weak keys.

Fields in java.util declared as Map

static Map

Collections.EMPTY_MAP The empty map (immutable).

Methods in java.util that return Map

static Map	Collections.unmodifiableMap(Map m) Returns an unmodifiable view of the specified map.
static Map	Collections.synchronizedMap(Map m) Returns a synchronized (thread-safe) map backed by the specified map.
static Map	Collections.singletonMap(Object key, Object value) Returns an immutable map, mapping only the specified key to the specified value.

Methods in java.util with parameters of type Map

static Map	Collections.unmodifiableMap(Map m) Returns an unmodifiable view of the specified map.
static Map	Collections.synchronizedMap(Map m) Returns a synchronized (thread-safe) map backed by the specified map.
void	AbstractMap.putAll(Map t) Copies all of the mappings from the specified map to this map (optional operation).
void	HashMap.putAll(Map t) Copies all of the mappings from the specified map to this one.
void	Map.putAll(Map t) Copies all of the mappings from the specified map to this map (optional operation).
void	Hashtable.putAll(Map t) Copies all of the mappings from the specified Map to this Hashtable These mappings will replace any mappings that this Hashtable had for any of the keys currently in the specified Map.
void	TreeMap.putAll(Map map) Copies all of the mappings from the specified map to this map.

Constructors in java.util with parameters of type Map

WeakHashMap(Map t)
Constructs a new WeakHashMap with the same mappings as the specified Map.

HashMap(Map t)
Constructs a new map with the same mappings as the given map.

Hashtable(Map t)
Constructs a new hashtable with the same mappings as the given Map.

TreeMap(Map m)
Constructs a new map containing the same mappings as the given map, sorted according to the keys' natural order.

Uses of Map in java.util.jar

Classes in java.util.jar that implement Map

class

Attributes The Attributes class maps Manifest attribute names to associated string values.

Fields in java.util.jar declared as Map

protected Map

Attributes.map The attribute name-value mappings.

Methods in java.util.jar that return Map

Map	Manifest.getEntries() Returns a Map of the entries contained in this Manifest.

Methods in java.util.jar with parameters of type Map

void	Attributes.putAll(Map attr) Copies all of the attribute name-value mappings from the specified Attributes to this Map.
